| /** |
| * Represents a parsed <l>Server</l> HTTP response header. |
| * |
| * <p> |
| * A name for the server. |
| * |
| * <h5 class='figure'>Example</h5> |
| * <p class='bcode w800'> |
| * Server: Apache/2.4.1 (Unix) |
| * </p> |
| * |
| * <h5 class='topic'>RFC2616 Specification</h5> |
| * |
| * The Server response-header field contains information about the software used by the origin server to handle the |
| * request. |
| * The field can contain multiple product tokens (section 3.8) and comments identifying the server and any significant |
| * sub-products. |
| * The product tokens are listed in order of their significance for identifying the application. |
| * |
| * <p class='bcode w800'> |
| * Server = "Server" ":" 1*( product | comment ) |
| * </p> |
| * |
| * <p> |
| * Example: |
| * <p class='bcode w800'> |
| * Server: CERN/3.0 libwww/2.17 |
| * </p> |
| * |
| * <p> |
| * If the response is being forwarded through a proxy, the proxy application MUST NOT modify the Server response-header. |
| * Instead, it SHOULD include a Via field (as described in section 14.45). |
| * |
| * <p> |
| * Note: Revealing the specific software version of the server might allow the server machine to become more vulnerable |
| * to attacks against software that is known to contain security holes. |
| * Server implementors are encouraged to make this field a configurable option. |
| * |
